Meraki Authentication Server Certificate Rotation - Feb 2023
Click 日本語 for Japanese
Overview
As part of a standard yearly certificate rotation to maintain Meraki Authentication security, Meraki will be rotating the RADIUS server certificate used for Meraki Authentication before its expiration 8 February 2023. The following is the expected impact and remediation steps.
Note: After the rotation date, Meraki Cloud Authentication with certificate based authentication will start to use a new certificate.
Meraki Authentication with Sentry Wi-Fi
Users of Meraki Authentication with Systems Manager Sentry Wi-Fi with devices which were online between the rotation date of 5 December 2022 and the expiration date of 8 February 2023 will have no user-visible impact.
Users with devices which were not online during that period simply need to associate to an SSID which will allow them to check in with dashboard for long enough to allow a check-in cycle to complete (~2 minutes) in order to receive the updated payload and resume normal operation
Meraki Authentication without Sentry Wi-Fi
Users of Meraki Authentication via certificate based authentication without Sentry Wi-Fi will need to 'trust' the new certificate with the below information upon associating to the Meraki Authentication SSID before 8 February 2023. Some devices may require the SSID to be "forgotten" before they will prompt to accept the new certificate.
Host: radius.meraki.com
Issued: DigiCert TLS RSA SHA256 2020 CA1
Expires: Nov 30 23:59:59 2023 GMT
Note: See the Meraki Authentication Radius Certificate below for the new certificate.
Trusted Access
Users of a Trusted Access configuration to an SSID will need to re-download their device's Trusted Access configuration from portal.meraki.com on or after the 8 February 2023 rotation date.
Certificate Details
Below is a copy of the certificate which users will be required to accept, as well as the plaintext output from reading the certificate with openssl:

FAQs
Q: What is changing?
A: Due to an approaching certificate expiration, Meraki will be rotating the RADIUS certificate for Meraki Cloud Authentication on February 8, 2023. This rotation is a standard yearly action taken to maintain Meraki Authentication security.
In some Systems Manager (SM) deployments, devices will automatically receive the new certificate and no further action will likely be required. However, there are certain deployment scenarios that may require action to be taken.
Q: How can an affected network be identified?
A: Any services relying on Meraki Cloud Authentication via certificates will be affected. This includes Sentry Wi-Fi, Trusted Access Wi-Fi, and any manual authentication relying on Meraki Cloud Authentication via certificates.
Q: Which network deployment scenarios require action to be taken?
A: Only SSIDs with Meraki Cloud Authentication using the RADIUS certificate for authentication will be affected.
If you are using this certificate for Meraki Cloud Authentication and have a network with any of the following deployment scenarios, your action may be required to manually accept the new certificate:
- If you have non-Systems Manager (SM) deployment networks
- If you utilize Meraki Authentication with Sentry Wi-Fi, but had devices offline between December 5, 2022 and February 8, 2023
- If you utilize a Trusted Access configuration to an SSID
Please refer to our documentation (above) for further network identification details and next steps.
Q: Is there an action needed to maintain connectivity?
A: Please refer to our documentation (above) to understand the expected impact and next steps for the different deployment scenarios.
If your network is affected, you may need to accept the new certificate for your devices to maintain connectivity before February 8, 2023.
Q: What happens if no action is taken by February 8, 2023?
A: If devices are still using the outdated RADIUS certificate after February 8, 2023, they may not be able to connect back to the Meraki Cloud Authentication SSID until the new certificate is accepted. Please see our documentation (above) for more details and next steps.
Q: How often is this certificate rotated?
A: This is part of a standard yearly certificate rotation to maintain Meraki Authentication security.
Q: Will this affect username or password authentication with Meraki Authentication?
A: This will only affect certificate-based authentication. If you are using Meraki Cloud Authentication with username/ password authentication that does not rely on this certificate (such as PEAP), your username and password will not be affected.
If you are using certificate-based authentication (such as EAP-TLS) where this RADIUS Meraki Cloud Authentication certificate is used, you will need to accept the new certificate before February 8, 2023.
Q: Is there any additional precautions which can be done to keep devices online?
A: It is recommended to have a backup SSID known by the devices. This could be a hidden PSK SSID, for example, and not broadcasted. However in the unlikely event that devices lose their connectivity, this SSID could be enabled to broadcast as a way for devices to come back online (and thus obtain the new certificate).
Q: Where can I go if I need additional assistance?
A: If you have additional questions or need assistance, please contact Meraki Technical Support.
